Comparison of the PPVT, PPVT-R, and intelligence tests used for the placement of black, white and hispanic EMR students

Comparisons of the revised PPVT (PPVT-R), the PPVT, and placement IQ tests were made with 114 EMR students, 46 white, 44 black, and 24 Hispanic. The PPVT and PPVT-R correlate substantially for all three ethnic groups, but neither the PPVT nor PPVT-R, correlates to a significant degree with the placement IQ tests. Sizeable mean score differences were obtained on the PPVT, PPVT-R, and placement IQ tests as a function of test differences and text x race interactions.
